Low-level laser therapy (LLLT) has been widely investigated as an adjunct technique for orthodontic treatment due to photobiomodulation effect. LLLT appears to be supportive for an orthodontic practice in terms of tooth movement acceleration, pain relief, and root resorption management. The decrease in these adverse effects will enhance the compliance in orthodontic patients, which could positively impact treatment outcomes. However, there seemed to be inconsistency in the impact of LLLT as well as its laser and treatment parameters. This scoping review aimed to evaluate the impact of different irradiation parameters on tooth movement acceleration, pain relief, and root resorption as well as to construct a protocol of LLLT in orthodontic practice. The search was conducted across PubMed, Scopus, Web of Science, Embase, Google Scholar, and the reference lists of identified articles. The last search was conducted on October 10, 2021 to identify experiments in humans regarding the application of LLLT as noninvasive treatment in orthodontic practice published between 2010 and 2021. However, they were excluded if they were not clinical research, if they did not report the source of laser, or if they were not relevant to tooth movement, pain perception, and root resorption, or if they were not available in English or in full-text. Following the systematic search and selection process, 60 articles were included in this review. A majority of included articles were published in the past few years. The findings of this review supported the application of LLLT in orthodontic practice with purposes of tooth movement acceleration and pain reduction. The positive impact of LLLT on root resorption had not been clearly evident yet. As this review demonstrated heterogeneity of both laser and treatment parameters, further research should be required to ensure the effectiveness of its specific parameters in orthodontic practice.
由于光生物调节作用，低强度激光疗法（LLLT）作为正畸治疗的辅助技术已得到广泛研究。在牙齿移动加速、疼痛缓解和牙根吸收管理方面，LLLT似乎对正畸治疗有辅助作用。这些不良反应的减少将提高正畸患者的依从性，这可能对治疗结果产生积极影响。然而，LLLT的影响以及其激光和治疗参数似乎存在不一致性。本综述旨在评估不同照射参数对牙齿移动加速、疼痛缓解和牙根吸收的影响，并构建正畸治疗中LLLT的方案。检索了PubMed、Scopus、Web of Science、Embase、Google Scholar以及已识别文章的参考文献列表。最后一次检索于2021年10月10日进行，以确定2010年至2021年间发表的关于LLLT在正畸治疗中作为非侵入性治疗应用的人体实验。然而，如果它们不是临床研究、未报告激光来源、与牙齿移动、疼痛感知和牙根吸收无关，或者不是英文或全文可得，则将其排除。经过系统的检索和筛选过程，本综述纳入了60篇文章。大多数纳入的文章是在过去几年发表的。本综述的结果支持LLLT在正畸治疗中用于加速牙齿移动和减轻疼痛的应用。LLLT对牙根吸收的积极影响尚未明确显现。由于本综述显示激光和治疗参数存在异质性，因此需要进一步研究以确保其特定参数在正畸治疗中的有效性。
